C7, acpi_als

This is an odd one: I've got a user with a system I built recently, who
comes to me to tell me the systems' frozen. I just looked this time,
before I did an init 3/init 5, and you can't click on anything... except
when I click on the uppermost right, and then I see wired, network and it
flashes, over and over.

Fastboot and Google pixel 3a

Has anyone used fastboot together with the Google Pixel 3a/3a XL phone? I cannot get it to be recognized and wonder if the version of fastboot available for Centos 7 may not be recent enough? It does work with older phones I have so the setup should be correct.

bcachefs-tools

Having a problem trying to complete make && make install of the bcache-tools.
After going through all the dependencies and insuring they are

how to increase DNS reliability?

Hi,

how can DNS reliability, as experienced by clients on the LAN who are
sending queries, be increased?

Would I have to set up some sort of cluster consisting of several
servers all providing DNS services which is reachable under a single
IP address known to the clients?

Just setting up several name servers and making them known to the clients
for the clients to automatically switch isn't a good solution because
the clients take their timeouts and users lacking even the most basic
knowledge inevitably panic when the first name server does not answer
queries.

Failed to start crond

Hi,

A couple of days ago, cron service stopped been running on my Centos 6.
When I try to start with "service crond start" I get this error :

Any ideas?

CentOS 8 partiitioning for reliability

I was just given a Dell R720xd with 160 GB memory and 12x 900 GB drives
that I plan to deploy as my home mail/file/backup server to replace an
aging Supermicro server running CentOS 7. Yeah, it's gross overkill for
that and I expect to tuck most of the drives away for spares.

How should I RAID and partition this beast for maximum reliability?

My current C7 system is using 1 TB of 2 TB capacity on the root partition
(4x 1 TB drives in RAID 10). /boot is 300MB/50GB.

some questions about tuned ...

Hi,

what is the point of running tuned as a daemon when dynamic tuning is
disabled?

What is the point of enabling dynamic tuning, especially when using the
supplied profiles like throughput-performance?

I haven't customized those by specifying any thresholds, and I don't see
any point in doing things like dynamically changing disk schedulers or
CPU governors depending on something recognized by tuned.

Why is there no measurable difference in power consumption between using
the powersave, throughput-performance and virtual-host profiles but a
very noticeable difference in performanc

SELinux settings for directory shared via NFS and samba?

Hi,

what do I need to do to share the same directory with both NFS and samba?
SElinux requires 'samba_share_t' for samba and 'nfs_t' for NFS, and AFAIC
I can't set both at the same time on a directory.

cryptsetup

On a just-built C 7 box, I've got this: boot, boot_efi, /, swap, and
export. Now, the last three are encrypted. For /, I'm trying to add an
escrow key. df -h shows me that / is /dev/dm-1. However, when I use
cryptsetup luksAddKey /dev/dm-1, it just comes back, without prompting me
for a password.

Missing PHP Redis package in Software Collections ?

Hi,

I'm currently fine-tuning OwnCloud on a CentOS 7 server. To configure
transactional locking, I need Redis with the corresponding PHP module.

Until recently the server has been running PHP 7.1. I simply installed
the 'redis' package as well as 'sclo-php71-php-pecl-redis', started
and/or restarted a handful of services, and things worked perfectly.

Now I'm upgrading my server to PHP 7.2, and it looks like there's one
package missing in the Software collections.

qemu-sparc, not to be confused with qemu-system-sparc

I installed CentOS 7.6 then installed all things QEMU on my machine. I have
a SPARC image I need to bringing up in a VM. I've been using

$ qemu-system-sparc -m 256 -hda solaris_v2-qemu_v2.2.0.disk -nographic

Can I use *qemu-sparc* to bring up my Solaris image:

If so, how?

Mate on Centos 7

I have been running Mate on Centos 7 for some time but it does not work very well on my HiDPI laptop screen. Today I found that I am running version 1.16 of Mate whereas the current version is 1.22. Undoubtedly many of the issues have been fixed since 1.16 was released in 2016...

However, EPEL only provides 1.16 - a release from 2016 - and nothing later.

What is the recommended way to upgrade to 1.22?

qemu-kvm-ev issues creating a VM

Hello,

not sure if it's the right place to post.

I have a VMWare Workstation 15.1 VM based on Centos 7.6 (Kenel 3.10.0-957)
with the CentOS-QEMU-EV repository enabled.

Version of qemu is: 10:2.12.0-18.el7_6.5.1

I'm having an issue with qemu-kvm-ev, basically it looks like I'm not able
to create any VM. I'm getting a "NMI watchdog: BUG: soft lockup - CPU#0
stuck for 22s! [kworker/0:0H:5]" and the installation will not proceed.

Everything works fine if I use the standard qemu-kvm

Community build services and EPEL8

Hello folks,

In the planning of next Community build services, a new question came up.

In the past we never allowed EPEL repositories to be used as external
repositories for SIGs. Doing so, would allow to build against EPEL
packages and not duplicate the work for maintainers in EPEL/SIGs.

However it would mean also building against a moving target which can be
difficult if EPEL policies are the same as today.

As EPEL 8 is also in the making it would be good to hear what SIGs think
about this specific issue.

Let us know !

HI All,

I have some remote computers - at times I issue commands to take screen

It might be a previous displayed item etc...

32-bit CentOS

It appears that CentOS 7 was the last one with a 32-bit version. I'm
trying to install it on an older laptop and having some trouble. I have
CentOS-7-i386-Everything-1810.iso and have verified it. Using either dd
or mediawriter to put a copy on a 16 GB thumb drive seems to work. But
then the laptop reports, "no boot image found". Note that the first 32 KB
of the iso is all zeros, meaning that there is no MBR or partition table
included.

According to the 0_README.txt on the CentOS mirrors, the Everything ISO,
"contains the complete set of packages for CentOS Linux 7.

part / --ondisk=sda --fstype xfs --size=20000 --asprimary

part /boot/efi --ondisk=sda --fstype efi --size=1000 --asprimary

CentOS, Red Hat, and IBM

CentOS community,

Today marks a new day in the 26-year history of Red Hat. IBM has
finalized its acquisition of Red Hat

What does this mean for Red Hat’s contributions to the CentOS project?

In short, nothing.

Red Hat always has and will continue to be a champion for open source

Creating KVM-based VM with virt-manager and virt-install on C7

Hi folks,

for learning purposes I create KVM-based VM with the virt-manager. Later
I get rid of the VM and repeat the "process" again. When recreating the
VM I always enter the same values into the wizard in virt-manager (i.e.
I want to speicfy a given MAC).

I'd like to "automate" this procedure, all of what I do in virt-manager
for creating the new VM, I' d like to do it with a bash script using
virt-install.

I' wndering if it is possible to "record" the values when I enter them
into virt-manager and extract those values for usage with virt-install?

Install of CentOS 7.6 On Dell PowerEdge R830 Hangs

All,

Seems like the latest CentOS 7.6 and I are not playing well together, these days.

I'm attempting to use our pxeboot setup to install the latest CentOS 7 on a

using RedHat binary packages?

AFAIK CentOS uses RedHat's source RPMs for building the next CentOS

I'm having a similar issue with an SFP on a Centos host, and am
searching for a way to view Optical RX/TX Power on the SFP.

From the switch side, I'm not seeing any RX Power from the Centos host.

Thanks in advance

SIG reports and the July newsletter

Due to two months of back-to-back travel, I am way behind on the July
newsletter. I still hope to get it done for Tuesday or Wednesday this week.

This month, we expect reports from:

* Alt Arch
* Cloud
* NFV
* Promo
* Storage

as per the listing at <a href="https://wiki.centos.org/SpecialInterestGroup" title="https://wiki.centos.org/SpecialInterestGroup">https://wiki.centos.org/SpecialInterestGroup</a>

As I haven't given any of these groups my usual two-week warning, I
imagine that this comes as a surprise. But if you can get me a report of
some kind in the next couple of days, it would be hugely appreciated. If
not, that's on me, not on you.

Thanks.

Migrate older disk image to new UEFI

Hi All - I have a CentOS 7 (image) that is fully updated. However its not
UEFI.

Is there a way to use an older computer and migrate my current image to be
UEFI so this new UEFI only computer I have will boot. Was hoping to not
have to completely re-install and setup for my needs.

Speakers needed: DefConf.US CentOS Dojo (August 14th, Boston)

Hi, folks,

I've had two of my speakers for the Dojo at DevConf.US fall through, and
I need to find replacements.

If you are interested in speaking at this event - August 14th, 2019 in
Boston - please submit your proposed talk here:
<a href="https://forms.gle/UgbodVpEUhnqHdNh6" title="https://forms.gle/UgbodVpEUhnqHdNh6">https://forms.gle/UgbodVpEUhnqHdNh6</a>

Talks should be about something you're doing with, or on, or for,
CentOS. Expect the audience to be very familiar with CentOS, and able to
grasp deep technical details.
